Question

the product of two successive multiples of 10 is 1200a) 20,30. b) 48,25 c) 60,20. d) 30,40​

Answer 1

Answer:

d) 30,40

Step-by-step explanation:

30×40=1200

and 30,40 are successive multiple of 10

Answer 2

Answer:

d) 30,40

Step-by-step explanation:

Next two Successive multiples will 30 and 40

take first multiple as x

second multiple will be x+10

According to question

x(x+10) = 1200

x power 2 + 10x = 1200

$x {}^{2} + 10x - 1200$

solve it .. values of x will come as -40 and 30

so we will eliminate negative value as multiple cant be negative

therefore X=30 and X+10 = 40

So the multiples are 30 and 40
